MULTI-SOURCE GASEOUS FUEL BLENDING MANIFOLD

摘要

A device, system, and method are provided for blending multiple fuels in multiple states and optimizing the blended fuel for parameters including cost, energy content, pressure, etc. In a primary fuel/supplemental fuel system, the present invention allows a user to consume as much primary fuel as possible even if the primary fuel is hampered by inconsistent pressure or quality issue, thus ensuring a downstream engine runs continuously.

主权项

1. A fuel blending system for an engine positioned proximate to a producing hydrocarbon wellbore, comprising:
a fuel tee interconnected to a first fuel train and a second fuel train, said fuel tee receiving a primary fuel from said first fuel train and a tertiary fuel from said second fuel train, said fuel tee interconnected to an engine having a maximum pressure; the first fuel train comprising:
a primary fuel input from the producing hydrocarbon wellbore supplying said primary fuel;a first primary check valve having an opening pressure that is less than said maximum pressure of said engine;a fuel reservoir positioned downstream from said primary check valve comprising a reservoir volume to store a predetermined volume of said primary fuel;a second primary check valve having an opening pressure that is less than said opening pressure of said first primary check valve; the second fuel train comprising:
a tertiary fuel input supplying a liquid tertiary fuel;a vaporizer configured to vaporize said liquid tertiary fuel into a gaseous tertiary fuel, said vaporizer regulating a pressure of said gaseous tertiary fuel to a tertiary pressure, said tertiary pressure is greater than said maximum pressure of said engine; anda tertiary check valve having an opening pressure that is less than said tertiary pressure.
